[Insight-users] Type error in CannyEdgeDetectionImageFilterConnectVTKITK.py

[Wilbur C. K. Wong]

Thanks for the reply.  You are right, I use Cableswig CVS to build the
ITK CVS, so that's why I've got "u" in the type associated with the
_p_itk__VTKImageImportTitk__ImageTfloat_2u_t_t.  However, I use VTK
CVS build also, I don't know which version of Cableswig is it using
when I build it with CMake.  There is no option for me to choose the
Cableswig CVS that I've got in the CMake console.

Please advice.

Wilbur
